Technical Description: Nidec Control Techniques SP1402
The Nidec Control Techniques SP1402 is a mid-range Frame 1 AC drive within the Unidrive SP (Solutions Platform) family. With a power rating of 1.1kW (1.5HP), this drive is designed for 200V class operation. It is the premier choice for machine builders who require a compact, highly dynamic drive capable of handling complex motion profiles and high-torque demands. The SP1402 is widely utilized in conveyor synchronization, packaging machines, and automated assembly systems.
High Performance and Scalability
The core strength of the SP1402 lies in its scalability. By utilizing the Solutions Modules (SM), the drive can be adapted to almost any industrial requirement. Whether the application requires high-speed Ethernet communication or a secondary encoder feedback loop, the SP1402 can be customized in minutes. The drive’s internal «Secure Disable» function (Safe Torque Off) provides an integrated safety solution that meets international standards, reducing the need for external safety contactors and simplifying the overall control cabinet design.
